Russian Defense Ministry Sergei Shoigu called Thursday on international organizations to take part in the humanitarian operation in Syria’s Aleppo.

“We are offering the international organizations working in Syria to join this operation,” Shoigu said.

Earlier in the day, the minister said Russia and the Syrian government had launched a joint large-scale humanitarian relief operation in Aleppo, establishing three corridors for civilians and one for militants wishing to lay down arms.
